Engine shuts off when it gets warm

99 Saturn SL2 idles and runs great. No OBD2 codes present. After about 5 minutes will suddenly stumble and die. At this point there is no spark at any wire. Someone recommended changing module--that worked for about 1/2 hour before it died. Coolant sensor--no fix. Tried to follow Haynes manual recommendations for checking module and crank sensor, but all it lists is the wiring diagram for up to 95 which has 2 plugs. I can't find diagrams or suggestions for single plug module.

Engine stalls cold or RPM
fluctuates at idle up and down or dies near idle.

This problem
is commonly caused by a dirty automatic idle speed control valve and
throttle valve but always run a OBD2 fault code as well as the
cleaning procedure. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control. If
the above cleaning doesn't cure your issues you need to have the
computer controlled automatic idle speed control system diagnosed and
repaired by a dealer or electronic engine control repair shop.
